I set out to create a 3D hex model using 2-1/2D extrusion in APEX and run Random Vibration from within Patran. My model was a machined aluminum component. My strategy was to create the base surfaces in the x-y plane and then "extrude" them into the z-direction of various heights to create a an aluminum component with RF "trenches". Once the 3D geometry was in place, it should have been trivial to mesh with hex elements using the 2.5D mesher. Or so I thought ...
I built the surfaces as shown

To create a hole in a planar surface would seem trivial for Apex. However, it took me quite a while to figure it out and so I thought it was worthy of note.
I had imported a bunch of IGES lines that defined the outer perimeter of the surface and two 180 degree arcs for the hole in the middle. I was really trying to avoid the old "Patran" approach of breaking curves to make a bunch of 4-sided polygons. I tried using the Drag Edge tool but there was a not a one-to-one matchup of curve segments on

As an MSC Apex Elite Agent, my company, DHL Consulting, is entitled to an MSC One license to be able to run MSC/Apex for demonstration purposes. About three weeks ago, I submitted a request form to MSC. The process is very streamlined and a couple days later I received by license.dat file.
However, after downloading and installing the software along with the MSC Licensing Utility, it shows you what your HostID is during installation. It was then I quickly realized that my HostID had changed due

I am, like most finite element analysts out there, new to MSC/Apex. I'm working through the process of coming up to speed and will document my findings along the way. This will help you, should you be evaluating the Apex software. Although I am an MSC Elite Channel Partner for the Apex product, I consider myself independent from MSC and will document my honest assessment of the Apex learning experience.

Before embarking to create a model from scratch, I have spent perhaps 15 hours to
